Summary:PROBLEM TO BE SOLVED: To provide a simple high-accuracy method of analyzing a thiourea-glue coexistent system. SOLUTION: In a flow analysis method in which the addition of a reagent, reaction and analysis are continuously carried out while a sample solution flows through a duct, the sample solution with thiourea and glue coexisting therein is adjusted to be sulfurically acidic and then led to a reagent adding part, and palladium is added to form a thiourea-paradium complex which is led to a measuring part. Thiourea is quantified from the turbidity, and glue is also quantified.
